Claims

[Claims for Utility Model Registration] 1. A set of at least two rectangular films made of flexible heat-fusible plastic and two sets of shingles are stacked together and the long sides 5 of the rectangle are heated together. They are fused and bonded to form a multi-layered flat cylindrical body, and each set of each layer is heat fused and bonded together along one upper end edge 6 of the short side of the rectangle. On the end side, each set has a check valve body 2 having a structure in which the inner layer coating 3 is shorter than the outer layer coating 4 and the lower end 7 of the inner layer cylinder body and the lower end 8 of the outer layer cylinder body form a step, and the flexible one-heat fusion. It consists of a bag body 1 made of an adhesive plastic film or the like, and the lower end of the outer layer cylinder of the check valve element' is attached by heat fusion so that it opens inside the bag body at the seam of the bag walls of the bag body. A bag-like container characterized by: 2. Connect the end 13 of the gap-forming piece 12 of the flexible heat-fusible plastic film to the check valve body, and create a tip holding gap 15 by bending and inserting it into the tip 14 of the check valve body. A bag-shaped container according to claim 1 of the claimed utility model registration.
